The green light on most network interfaces represents the network speed, while the yellow light represents data transmission.
Although various network devices are different, in general:
Green light: long light—represents 100M; no light—represents 10M.
Yellow light: long on — means no data is being sent or received; flashing — means data is being sent or received
The Gigabit Ethernet port (1000M) directly distinguishes the status according to the color, not bright: 10M/green: 100M/yellow: 1000M.

With the advent and popularization of 5G networks, the original lowest 10M network has been replaced by a 100M network.

If one LED on the RJ network port is always on, it usually indicates a 100M network or higher, while the other LED flashes, indicating that data is being transmitted. Subject to network equipment.

In order to reduce costs, some low-end network ports have only one LED. A long light indicates that the network is connected, and a blinking indicates data transmission. These are all completed by the same LED.

The LED in the RJ network port connector provides us with a more intuitive help to distinguish the status of the network equipment. With the changes in market demand, the RJ connector with LED is a better choice for selection.
